ATTACHMENT FOR ELECTRIC TROLLEYS.

SPECIFICATION forming part of Letters Patent NO. 631,596, dated August22, 1899. Application filed February Q, 1899. Serial No- 705,063. (Nomodel.)

To all whom it may concern: Be it known that we, HERMAN STUEMPFLE andJOHN DELANE, of Terre Haute, in the county of Vigo and State of Indiana,have invented certain new and useful Improvements in Attachments forElectric Trolleys; and we do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form part of thisspecification.

This invention relates to trolley-wheels and trolley-poles of electricrailways, and has for its object to provide an improved attachment,adapted to be secured to the pole, by means of which a sleet-wheel maybe attached when necessary or an auxiliary trolley-Wheel brought intouse in case of accidental breaking or wearing out of the ordinarytrolleywheel or the harp or forked socket in which it is journaled.

With these objects in view the invention consists in the improvedconstruction, arrangement, and combination of parts hereinafter fullydescribed, and afterward specifically pointed out in the appendedclaims.

In the drawings, Figure 1 is a view in side elevation illustrating ashort length of the trolley-wire with a sleet-wheel in contact with itand the usual trolley-wheel and pole, the wheels being partlybroken awayand the sleet-wheel being secured by means of an at tachment constructedin accordance with our invention. Fig. 2 is a detail sectional view onthe broken line- 2 2 of Fig. 1. Fig. 3 is a similar sectional View onthe line 3 3 of Fig. 1. Fig. 4 is a View similar to Fig 1, illustratingmy attachment in modified form. Fig. 5 is a detail sectional view on theline 5 5 of Fig. 4, and Fig. 6 is a view of the trolley attachmentdetached.

Like numerals of reference mark the same parts wherever they occur inthe various figures of the drawings.

Referring to the drawings by numerals, 10 indicates the ordinarytrolley-pole, 11 the harp or forked socket secured on the end thereof,and 12 the ordinary trolley-Wheel pivoted between the arms of the forkedsocket.

.13 indicates the trolley-wire, and 14 is a toothed sleet-wheel whichwhen used acts as a substitute for and takes the current off the wire inthe same manner as the ordinary trolley-wheel, in addition to breakingup the sleet or ice on the Wire. The sleet-wheel 1 L is mounted in aharp or forked socket 15, similar in form to harp 11, which harp 15 ismountedon the end of a rod 16, which forms the main body of myattachment. This rod 16 is curved outward at 17 to pass around thetrolley-wheel 12, is provided with a block 18 on its inner side, with aV-shaped groove in its face, to bear against the stem of the harp 11,and is formed at its inner end of an open-ring shape, as at 19, topermit it to he slippedlaterally upon the trolley-pole 10. The upperinner face of the ring shape 19 is made angular, as at 20, to permit offitting trolley-poles of some slight variation in size,

and a set-screw 21 adapted to bear against the lower side of thetrolley-pole, firmly secures the attachment in position.

The construction of our attachment will be readily understood from theforegoing. When it becomes necessary to use the sleet-wheel, the.attachment may be quickly clamped upon the trolley-wheel, the outwardcurve 17 of rod 16 closely hugging the trolley-wheel in its groove,forming a rigid brace for the attachment and a contact-surface for thetrolleywheel for almost half its circumference.

Our attachment may be provided with an ordinary trolley-wheel instead ofthe sleet-wheel, and one of them may be carried on each car for use incase the ordinary trolley gets stuck and fails to rotate or of anyaccident which renders the use of a temporary trolley-wheel a necessity.

In Figs. 4 and 5 we have illustrated a modified construction, in which10 is the trolleypole, 22 a harp or forked socket, and 23 either a plaintrolley-wheel or a sleet-wheel. The stem 24 of the forked socket isshaped at its end similarly to the inner end of the bar 16 and has aset-screw 25 to clamp the trolley-pole. In the use of this modificationeach car is supposed to carry an extra Wheel in a forked socket thusconstructed. In ordinary weather the extra outfit will be provided witha plain trolley-wheel and in sleety weather with a sleet-wheel. Shouldthe ordinary trolley wheel 'or its harp or socket become broken orotherwise disabled, it can be at once taken off and an extra onesubstituted, the extra outfit with sleet-wheel being substituted whennecessary.

\Vhile we have illustrated and described eflicient means for carryingout our invention, we wish it to be understood that we do not limitourselves to the exact forms and constructions shown, as many slightchanges and variations therefrom might suggest themselves to theordinary mechanic which would be clearly included in the limit and scopeof our invention.

Having thus fully described our invention, what we claim to be new, anddesire to secure by Letters Patent of the United States, is-

1. An attachment for trolleys comprising a harp or forked socketprovided at its inner end with an angular clamp open at one side, aset-screw through the side thereof, and a substitute wheel journaled inthe arm end of the socket, all substantially as described.

2. An attachment for trolleys comprising a bar curved laterally to fitin the groove of the ordinary trolley-wheel and carrying a clamp at itsinner end to secure it to the pole, and a substitute wheel at its outerend, substantially as described.

3. An attachment for trolleys comprising a bar provided at its inner endwith means whereby it may be slipped sidewise upon the pole and clampedthereon, and with a substitute wheel at its outer end, substantially asdescribed.

at. A11 attachment for trolleys comprising a bar adapted to be slippedlaterally upon the pole, a clamp to hold it thereon and a substitutewheel at its inner end, the bar, intermediate of its ends being curvedoutward to snugly hug in the groove of the trolley-wheel, substantiallyas described.

5. The herein-described trolley attachment consisting of the bar 16curved outwardly at 17 to snugly fit in the groove of the trolleywheel,the inner end of said bar being constructed to form an open-sided ring,angular in section, the set-screw threaded through the bottom of saidring and adapted to bear against the lower side of the trolley-pole, theV-shaped block on the inside of bar 16 to bear against the stem of theharp or socket of the trolley-wheel, and the sleet-wheel j ournaled in aharp or socket secured to the outer end of the bar 16, all substantiallyas and for the purposes set forth.

6. As an article of manufacture an attachment for trolley-poles curvedlaterally near its middle portion to fit a trolley-wheel and having astem on its outer end to fit a socket, an elongated open-ring portion onits inner end having a set-screw to form a grip and an intermediateV-shaped bearing-block in line with the bore of the ring whereby theattachment is prevented from twisting and kept in line on thetrolley-pole, substantially as described.

In testimony that we claim the foregoing as our own we affix oursignatures in presence of two witnesses.
